New Study Details How Mass-Scale Reuse Could Help End 'Scourge' of Plastic Pollution
"Ramping up reuse systems is the most sensible approach to replacing single-use plastics and dramatically cut plastic production," said one advocate. "The plastics treaty discussions this week must lay the groundwork for this transformation."
May 31, 2023
As world leaders convened in Paris on Tuesday for negotiations regarding a global plastics treaty that the United States and plastic producers are hoping will take a limited approach and center recycling, a new study showed how investing in the "mass adoption of reuse systems" would make a far bigger impact in cutting plastic pollution and reducing carbon emissions that are derived from the making of plastic.
The Break Free From Plastic movement commissioned the study, Making Reuse a Reality, by the Global Plastics Policy Center at the University of Portsmouth in the United Kingdom. Researchers drew from 320 articles and papers as well as dozens of new interviews with experts on reuse systems.
The researchers found that shifting to reuse systems on a mass scale would require a phasing-in process but could ultimately cut plastic pollution by 30% by 2040.
"The scourge of single-use packaging continues to grow at a pace beyond the capacities of existing waste management systems," said Von Hernandez, global coordinator for Break Free From Plastic. "Prevention is key; ramping up reuse systems is the most sensible approach to replacing single-use plastics and dramatically cut plastic production. The plastics treaty discussions this week must lay the groundwork for this transformation."
As Tiza Mafira, executive director of Plastic Bag Diet in Indonesia, explained in a video released by the research team, people around the world have for years turned to reusable materials to replace single-use plastic packaging in their own homes.
A mass transition would require similar efforts by businesses around the world, Mafira said.
"We are drowning in plastic pollution, and almost half of it is just packaging," she said. "Instead of delivering products in disposable plastic, [in a reuse system] businesses create durable and reusable packaging that gets returned to them and used over and over. Instead of throwing away bottles, they get refilled. Instead of trashing food takeaway containers, they get washed and reused."
Making Reuse a Reality - Explainer
Seventy-seven percent of the reuse experts interviewed for the study said standardizing packaging and developing tracking methods would be "key enablers" to shift to a reuse system on a large scale.
The experts suggested using tagging systems including QR codes, Radio Frequency Identification Device tags, or Near Field Communication chips, as well as methods to make returning reusable packaging as easy as possible for consumers.
"Interviewees emphasized the need for easily accessible drop-off points that are relevant to where End-of-Use occurs. The system should acknowledge the return, which can be efficiently done through code or tag readers or by staff," reads the report. "The return points should be clearly identifiable with a reuse logo and instructions and should be located in highly accessible areas."
After consumers return their packaging, it would be cleaned and pooled at central "hubs" before being delivered back to stores and factories.The study suggests a four-phase rollout:
- Laying the foundations for reuse, including government action and an end to policymakers' focus on recycling over reuse;
- Growing reuse systems by starting in "closed systems" such as sports arenas and music festivals—where consumers' use of reusable food and drink containers could help to build public acceptance—followed by to-go containers at restaurants;
- Accelerating and scaling up reuse, including the development of large hubs to sort, clean, and return packaging to producers; and
- Establishing reuse as the new norm.
Mafira called for reuse "to be right at the heart of the plastic treaty discussions this week," and a "high ambition coalition" of countries including Norway and Rwanda has called for binding provisions in the treaty that would require "parties to commit to targets in key areas" including reuse systems.
The coalition says a legally binding instrument is needed to end plastic pollution by 2040, but countries including the U.S., China, and Saudi Arabia are joining many plastics and chemical companies in supporting voluntary "national action plans" that would allow individual countries to decide how to reduce their plastic production and use.
The U.S. produces more plastic waste per person than any other country, according to a study published in Science Advances in 2020.
"If we're serious as a global community about averting climate change and about addressing the three planetary crises of biodiversity loss, pollution and climate change, we have to be thinking about reducing plastic production," Jane Patton, campaign manager for plastics and petrochemicals at the Center for International Environmental Law, toldThe Washington Post on Tuesday.
Critics including several members of Congress have warned the Biden administration that its focus on reducing plastic pollution is too narrow, with Sen. Jeff Merkley (D-Ore.) and Rep. Jared Huffman (D-Calif.) telling President Joe Biden in a letter last week that he should recognize the threats to "public health, ecosystems, and our global climate" that are posed by plastic production.
"As one of the leading drivers of this crisis, the United States has a leadership opportunity and an obligation to help move the world responsibly in the right direction," wrote Merkley and Huffman. "The international legally binding instrument is an unprecedented opportunity to address our plastic pollution crisis and our climate crisis in tandem. We urge you to stop thinking of this as just as a pollution problem and to recognize it as the public health, justice, and climate crisis that it poses."
The University of Portsmouth study, said Global Plastics Policy Center director Steve Fletcher, shows that a scaled-up reuse system "has huge untapped potential to end plastic pollution."
"What we need now," he said, "is a clear vision for reuse and the right support to mainstream it."
